I just saw this show in NYC called The Boy from Oz, about Peter Allen, an Australian born actor/songwriter.

But long story made short, in one set on the scene, in his living room, there was a poster up of a Koala Bear wearing what looked like a captain's hat and it said, "Captain Koala." Was that an Old Qantas Advertisement perhaps?

On another poster, it showed Qantas Livery on the tail of a plane with what looked like the a red winglet just in front of it, suggesting it was the photo of a QF 747-400. looked similar to the following...

How long has the 747-400 been around? This part of the movie takes place in the 80's so I assume it was a time error? Also, in the same poster, was what looked like a Oneworld Emblem. How long they been around? (Gosh, I am turning into an ANAL aviation geek methinks! )

In the US market, QF used a koala (with a grumpy voiceover- koalas don't talk by the way- you have to explain EVERYTHING to some people in this forum) to promote the airline.
Commercials usually ended with the line "I hate Qantas". The joke was QF would bring planeloads of tourists to Australia and the koala would get too many visits in the zoo, etc. I used to have a QF calendar and one picture was of the koala with a QF captain's hat.
However, my understanding is koalas weren't used in the Aussie market. I once saw some Channel 10 "worlds best/worst/sexiest/irrelevant commercials/momments/home videos" special with a talentless Daddo, and low and behold, there was a spot about Americans referring to koalas as promoters for QF. The Aussies didn't understand the reference (and Daddo neglected to fill them in) so they laughed at the yanks.
